Problems solved by technology

[0004] Existing cable path detectors are usually equipped with mobile devices, which are in the state of being pushed by people during detection, so they can only detect along the path pushed by people, so the detection coverage area is low, the detection range is small, and because the detection device moves in one direction , the path passed through is only detected once, resulting in low detection efficiency

Embodiment 1

[0028] like Figure 1 to Figure 3 As shown, the underground cable path detection device described in this embodiment includes a device main body 10, a first detection end 11 arranged on one side of the device main body 10, a second detection end 12 arranged above the first detection end 11, and formed on An accommodation cavity 14 inside the top end of the device main body 10; an opening is provided at the end of the accommodation cavity 14 away from the first detection end 11, and a mounting plate 13 is provided at the side of the accommodation cavity 14 opening away from the first detection end 11;

[0029] The side of the mounting plate 13 away from the housing cavity 14 is provided with a geared motor 21 for outputting power; the output shaft of the geared motor 21 extends into the interior of the housing cavity 14 and is linked with a reciprocating assembly 40 , the reciprocating assembly 40 Including a push rod 46, the end of the push rod 46 penetrates the inner wall of ...

Embodiment 2

[0037] like Figure 4 as well as Figure 5 As shown, the underground cable path detection device described in this embodiment is a further improvement made on Embodiment 1. The transmission rod 23 includes a first rod body 231 and a second rod body 232, and the first rod body 231 and the second rod body 232 A connection assembly 50 is provided therebetween for forming a detachable connection between the first rod body 231 and the second rod body 232 .

[0038] When in use, when the second detection end 12 is required to be in a relatively stopped state, and the second detection end 12 is required to detect only a certain path, the first rod body 231 is disconnected from the second rod body 232 through the connecting assembly 50, at this time the first rod body 231 and the second rod body 232 The second detection end 12 is in a relatively static state, and only detects the bottom corresponding to its rest position.

[0039] refer to Figure 4 The connection assembly 50 inclu...

Embodiment 3

[0046] like Image 6 As shown, the underground cable path detection device described in this embodiment is a further improvement made on Embodiment 2. A central processing unit 60 is integrated inside the main body 10 of the device, and the central processing unit 60 includes a detection unit 61, Comparison unit 62, preset unit 63, calculation unit 64, control unit 65;

[0047] The detection unit 61 is used to detect the signal of the underground cable, and output the result of signal strength to form a detection value, and at the same time, output the position information of the generated signal;

[0048] The preset unit 63 is used to preset the standard for the detection signal to be rechecked to form a standard value;

[0049] The comparison unit 62 is used to compare the detection value obtained by the detection unit 61 with the standard value, and output the comparison result;

[0050] The calculation unit 64 is used to calculate the calculation path of the second detec...

Abstract

The invention provides an underground cable path detection device, and relates to the technical field of cable path detection, and the underground cable path detection device comprises a device main body, a first detection end, a second detection end, an accommodation cavity, a mounting plate, and a gear motor. An output shaft of the gear motor extends into the accommodating cavity and is linked with a reciprocating assembly, the reciprocating assembly comprises a push rod, and the tail end of the push rod penetrates through the inner wall of the accommodating cavity and is fixedly connected with the first detection end; an output shaft of the gear motor is in transmission connection with a transmission rod through a conveyor belt, the end, away from the transmission rod, of the transmission rod extends to the position above the containing cavity and is in linkage with a swing assembly, and the swing assembly comprises a swing rod connected with the second detection end; and the device main body can repeatedly detect the moving path and the positions on the two sides of the moving path for multiple times, so that the device main body can cover a larger area during detection, the detection efficiency is high, and omission is avoided during detection due to multiple times of detection.

Description

technical field [0001] The invention relates to the technical field of cable path detection, in particular to an underground cable path detection device. Background technique [0002] In the process of cable maintenance, relocation, and fault finding, it is often encountered that the cable ledger is lost, and the direction and buried depth of the cable cannot be confirmed, especially for some old cables. Therefore, cable path detection is required. In this process, it is necessary to use Cable path detector. [0003] The basic principle of the cable path detector is to use the detection coil to sense the electromagnetic field caused by the alternating current loaded on the cable to be tested. When performing path detection, it is necessary to use a signal generator to transmit an audio signal to the cable and use the host computer to receive it. [0004] Existing cable path detectors are usually equipped with mobile devices, which are in the state of being pushed by people...
